Somewhere in southern Morocco, between the silence of the dunes and the relentless Saharan sun, roughly 1,300 people will line up in April 2026 to do something most of us would call unreasonable. They’ll strap on backpacks loaded with everything they need to survive — food, sleeping gear, medical supplies — and run approximately 250 kilometers across one of the most unforgiving landscapes on Earth. No hotels. No support vehicles. No quitting without consequences.
This is the Marathon des Sables 2026, the 40th edition of a race that has earned its reputation as the toughest foot race on the planet. And if you’re reading this, you’re probably considering joining them.
I wrote this guide to give you the full picture — not the glossy brochure version, but the real, practical, occasionally uncomfortable truth about what it takes to register, prepare for, and survive the MDS. Whether you’re a seasoned ultrarunner eyeing the Legendary edition or someone who just discovered the race exists and can’t stop thinking about it, this is your roadmap from couch to Sahara.

What Is the Marathon des Sables? A Race Unlike Anything Else
The Marathon des Sables — MDS for short — is a multi-stage ultramarathon held annually in Morocco’s Sahara Desert. It was founded in 1986 by Patrick Bauer, a French concert promoter who crossed the Sahara solo and decided the experience was too transformative to keep to himself. Four decades later, more than 30,000 people have taken on his challenge.
The concept is deceptively simple: cover roughly 250 km on foot over six timed stages across seven days. You carry your own food and gear. The organization provides water and open-sided Berber tents shared with seven strangers who, by day three, feel like family. That’s it. No aid stations stocked with energy gels. No massage therapists at mile 20. Just you, your backpack, and an endless expanse of sand, rock, and dried riverbeds.
The MDS is often described as a Sahara ultramarathon, and that’s technically accurate. But it doesn’t capture the full experience. This is part endurance race, part survival exercise, part spiritual retreat. The 2025 edition saw a completion rate of roughly 95% — proof that finishing isn’t about being elite. It’s about being stubborn enough to keep moving.
Marathon des Sables 2026 Dates, Distance, and Race Format
When does the race take place?
The 40th edition of MDS Legendary runs from April 3 to April 13, 2026. That’s eleven days in Morocco, with nine spent deep in the desert near Ouarzazate Province in the country’s south. Mark these dates now — your entire training calendar will revolve around them.
What is the total distance of the Marathon des Sables?
The official figure is approximately 250 kilometers, but field reports from the 2025 edition and early indications for 2026 suggest the actual distance could reach around 270 km. The organizers typically keep exact stage distances under wraps until just before the race. The distance is spread across six timed stages that range from manageable to monstrous.
The six stages: what each day demands
Stages 1 through 3 (April 5–7): Opening stages covering 32 to 40 km each. These aren’t warm-ups — they’re calibration. Your body learns to cope with heat, pack weight, and terrain that shifts from soft sand to jagged rock without warning.
Stage 4 — “The Long One” (April 8–9): This is where the race earns its reputation. Roughly 100 km to be covered within a 48-hour window, day and night. You’ll need your headlamp. You’ll need mental reserves you didn’t know you had. Veterans call this the hardest thing they’ve ever done — and the most liberating.
Stage 5 — The Marathon (April 10): A classic 42.2 km marathon distance, but with a reverse start: the slowest runners go first. This means the leaders cross the finish line last, creating an electric atmosphere as the field converges.
Stage 6 — The Finale (April 11): Approximately 21 km — a half marathon distance — ending with the medal ceremony. This stage isn’t about performance. It’s about celebration.
Marathon des Sables Cost: What You’ll Actually Spend
The registration fee is only part of the equation. Here’s what the full financial picture looks like:
| Package | Price (EUR) | Price (USD approx.) | What’s included |
|---|---|---|---|
| Classic | €3,950 | ~$4,580 | Registration + 2 hotel nights in Ouarzazate + transfers + medical support |
| Superior | €4,350 | ~$5,050 | Registration + 2 nights at the 5-star Berbère Palace + special dinner |
These figures don’t cover flights to Morocco, freeze-dried food and gear (budget an extra €300–500 / $350–580), or additional hotel nights if you arrive early or stay late. A realistic all-in budget for a participant coming from Europe runs between €5,000 and €6,000 (~$5,800–$6,950). Both packages are priced equally regardless of your country of residence, and both include free postponement insurance until March 27, 2026.
Marathon des Sables Registration: How to Secure Your Spot
Registration is handled exclusively through the official website at marathondessables.com. For the 2026 Legendary edition, enrollment opened on June 11, 2025. Capacity is limited to roughly 1,200–1,500 participants, and the race fills up — especially for a milestone anniversary edition like the 40th.
You can pay in installments based on your registration date, but your spot isn’t confirmed until the full amount is settled. During registration, you’ll choose your package (Classic or Superior), your arrival airport (Marrakech or Ouarzazate), and optionally your hotel roommate.
The race is open to all nationalities. The minimum age is 18. You can run or walk — the minimum required pace is 3.5 km/h, which means committed walkers can absolutely finish this race.
The Medical File: Skip This and You Won’t Start
The medical requirements aren’t bureaucratic theater — they’re your literal entry ticket. The regulations demand a complete medical file including an official medical certificate on the organization’s own form, plus a resting electrocardiogram (ECG) with its printed tracing. These documents must be signed within 30 days before the race — meaning no earlier than March 3, 2026.
Book your appointment with a sports physician now. If you show up to the medical check in Morocco on April 4 without your paperwork, you’ll face a €200 (~$230) fine and a one-hour time penalty per missing document. Worse: the medical team reserves the right to pull you from the race entirely if they judge you unfit. Don’t let months of preparation collapse over a forgotten form.
Self-Sufficiency: What Goes in Your Pack
Food strategy
Self-sufficiency is what separates the MDS from every other ultramarathon on the calendar. You carry all your food from the evening of April 3 through lunch on April 11. The minimum requirement is 2,000 calories per day across the six race days — 12,000 calories total. Random inspections happen, and any shortfall costs you a two-hour time penalty.
Most participants rely on freeze-dried meals, nuts, energy bars, and dried fruit. Target pack weight at the start: 9 to 12 kg (the official minimum is 6.5 kg excluding water). One piece of advice that experienced finishers all agree on: test every single meal during training. The Sahara is not the place to discover your stomach rejects a particular brand of dehydrated pasta.
Mandatory equipment
Gear checks happen on Day 2 and they’re thorough. Missing items mean harsh time penalties or outright disqualification:
| Item | Penalty if missing | Why it matters |
|---|---|---|
| Backpack | Disqualification | Carries everything you own |
| Sleeping bag | 3-hour penalty | Desert nights drop to 10°C |
| Compass (1° or 2° precision) | 3-hour penalty | Emergency navigation in sandstorms |
| Headlamp (400 lumens + batteries) | 1-hour penalty | Essential for the overnight long stage |
| Metal-blade knife | 1-hour penalty | General use and emergencies |
| Signaling mirror + whistle | 1-hour penalty | Traditional rescue tools |
| €200 / ~$230 cash | 1-hour penalty | Emergency expenses or fines |
| Sunscreen (50ml minimum) | Time penalty | You’ll spend 8–12 hours daily under direct sun |
| 10 safety pins | Time penalty | Field repairs |
You’ll also receive a “marathon bag” from the organization containing your road book, race ID, and GPS tracker — losing the tracker costs €200 (~$230).
Getting There: Logistics from Airport to Desert Camp
Airports and transfers
Two main options:
Marrakech Menara Airport: The most popular choice, with cheaper and more frequent flights. The organization runs shuttle buses on April 1 and 2, departing in the morning. The ride crosses the High Atlas Mountains via the Tizi n’Tichka pass — a five to six-hour journey that doubles as one of the most scenic drives in North Africa.
Ouarzazate Airport: Fewer flight options but direct arrival. Hotels are just 10 minutes by taxi. You’ll need to arrange your own airport-to-hotel transfer. Your assigned hotel is communicated a few weeks before the event.
Return flights: If flying out of Marrakech, book your departure after 2:00 PM on April 13. The overland transfer from Ouarzazate takes hours, and you don’t want to miss your flight after everything you’ve been through.

Accommodation in Ouarzazate
Ouarzazate — often called “Africa’s Hollywood” for the number of international films shot there — serves as your base before and after the desert. Your registration includes two hotel nights in shared double rooms. You can request a specific roommate through the website; otherwise, assignment is based on language, nationality, and gender.
On the free day after the race (April 12), you can visit the UNESCO World Heritage site of Aït Benhaddou, attend the awards ceremony, and enjoy the gala dinner. Ouarzazate sits at the gateway to the Sahara, and the surrounding landscapes — ancient kasbahs, dramatic gorges, palm-lined valleys — are worth exploring if you have the energy.
Weather and Terrain: What Your Body Will Face
The desert isn’t just hot — that’s the first mistake newcomers make. In April, daytime temperatures average around 30°C, spiking to 40°C at midday. But at night, temperatures drop to an average of 14°C and can dip to 10°C in exposed areas. That 20-degree swing between day and night demands layered, technical clothing.
The terrain alternates between towering sand dunes (including those near the famous Merzouga erg), vast rocky plateaus known as hamada, and dry riverbeds called wadis. Recent editions have featured heavy sand — expect more of the same in 2026. This is why gaiters (sand guards that attach to your shoes) rank among the most critical pieces of gear you’ll carry.
Wind averages around 18 mph in April and can escalate into sudden sandstorms that reduce visibility to near zero. Your compass and signaling mirror aren’t formalities — they’re lifelines.
Marathon des Sables Training: How to Build a Desert-Ready Body
A full training program depends on your current fitness level and timeline, so I won’t pretend to offer a one-size-fits-all plan. But these principles are consistent across every finisher I’ve spoken with:
Start at least six months out. Preparing for the MDS isn’t just about logging miles. You need long-distance sessions (30+ km) carrying a loaded pack weighing 10–12 kg. This conditions your back, shoulders, and feet for what’s coming.
Train on varied surfaces. Sand demands 30–50% more energy than asphalt. If you don’t have dunes nearby, train on grass or soft dirt.
Test everything before race day. Shoes, socks, gaiters, food, sleeping bag — all of it. Blisters are the number-one reason participants withdraw, and the Sahara does not forgive surprises.
Don’t neglect heat acclimatization. If you’re coming from a cold climate, gradually increase heat exposure in your final weeks of training — even if that means wearing extra layers during workouts.
Not Ready for 250 km? The Autumn Editions Are a Smart Starting Point
Not everyone dreaming of the Sahara is ready to tackle 250 km in one go. The organization offers shorter formats in autumn 2026 that deliver the MDS experience at a more accessible scale — and they’re the ideal way to prepare before committing to the Legendary edition.
MDS 120 Morocco (October 2026)
Running from October 2 to 10, 2026, near Ouarzazate. You choose between three distances — 70, 100, or 120 km — spread across three stages. The flexibility is the headline: you can change your distance during the race based on how you’re feeling. The program includes four hotel nights and four nights at the desert bivouac, with a registration fee of approximately €2,150 (~$2,490). The experience also includes a visit to the Aït Benhaddou UNESCO site.
This edition operates under food self-sufficiency — you carry your own meals — but the shorter duration and distance make it a realistic entry point.
MDS Trek Morocco (October 2026)
If you’re drawn more to exploration than competition, this format was designed with you in mind. Running October 11 to 20, 2026, covering 70 to 120 km across four stages. The key difference: full board meals are provided, and you only carry a light daypack. The camp features shared tents with mattresses, Berber showers, and massage sessions. The organization handles your heavy luggage. Ten days of total disconnection in the heart of the Moroccan Sahara, with wellness workshops on topics like breathing techniques and nutrition.
MDS Handi — Inclusivity in the Desert
In an inspiring move, the organization launched a dedicated format for people with disabilities and wheelchair users, following a successful first edition in 2024. Each team consists of four people (one wheelchair athlete and three assistants), with the organization providing specially designed off-road racing wheelchairs. The route covers approximately 70 km across three stages, with adapted pathways, accessible facilities, and a specialized rehabilitation medical team. The 2026 edition will welcome 50 teams.
Quick Comparison: Which Edition Fits You?
| Edition | Dates | Distance | Cost | Level |
|---|---|---|---|---|
| Legendary | April 3–13 | ~250 km | €3,950+ / ~$4,580+ | Advanced |
| MDS 120 Morocco | October 2–10 | 70–120 km | ~€2,150 / ~$2,490 | Intermediate |
| MDS Trek Morocco | October 11–20 | 70–120 km | TBA | Beginner/Intermediate |
| MDS Handi | Autumn 2026 | ~70 km | TBA | All levels |
Cancellation and Deferral Policies
Given the investment involved, here’s what you need to know if your plans change:
Legendary edition: Free deferral to the next edition is available until March 27, 2026 — seven days before departure. After that date, no deferral is possible. Only one deferral per registration is allowed.
MDS 120 Morocco: Free deferral is available until a specified date, after which a €250 (~$290) fee applies. Full refund schedules are detailed in the official regulations.
One more thing: buy flight tickets with cancellation and change insurance. Travel restrictions can shift, and the organization explicitly recommends this in their own regulations.
Sustainability: A Race That Respects the Desert
The MDS operates under a strict ethical charter aligned with the International Trail Running Association’s standards. The organization enforces a zero-waste policy on course: all water bottles are numbered and assigned to individual runners, and any discarded bottle is traced back to its owner for time penalties. Doping substances banned by the World Anti-Doping Agency are prohibited, as are certain strong painkillers during the race due to their risks in severe dehydration conditions.
New for 2026: the organization is encouraging European participants to explore more sustainable travel options to Morocco — including train-and-ferry combinations as alternatives to flying. The journey itself becomes part of the adventure.
Where Does the Marathon des Sables Take Place?
The MDS Legendary is held in Morocco’s southern desert, specifically in the Ouarzazate region — a territory defined by towering mud-brick kasbahs, sweeping desert plains, and some of the most dramatic scenery in North Africa. The exact course changes every year, but it typically weaves through golden sand dunes (like those near Merzouga), vast stone plateaus, and dry wadis carved into the earth like natural trenches.
Morocco isn’t just a backdrop for this race — it’s a central character. From the moment you land in Marrakech or Ouarzazate, you’ll watch the landscape transform: the ochre walls of the old medina give way to the snow-capped Atlas Mountains, which eventually dissolve into open desert. This visual journey is inseparable from the MDS experience, and it’s the reason Patrick Bauer chose this country in 1986 and never left.

Ten Final Tips from the Field
- Start your medical checks now — don’t wait until the last week.
- Pack weight is your real enemy — every extra gram compounds after kilometer fifty.
- Prioritize your feet — invest in proper shoes and test them for months. Blisters are the top reason people drop out.
- Respect the night — a good sleeping bag means real sleep means faster recovery.
- Carry enough sunscreen — you’ll spend 8 to 12 hours daily under direct desert sun.
- Bond with your tent mates — morale makes an enormous difference, and Sahara friendships last.
- Run your own race — 95% of participants finish. The secret isn’t speed. It’s consistency.
- Register early — spots are limited and the 40th edition will draw heavy demand.
- Plan extra time in Morocco — after nine days in the desert, you’ll want a day or two to explore Marrakech or Ouarzazate.
- Enjoy it — yes, it will be brutal. But every finisher says the same thing: the hardest week of my life, and the most beautiful.
The Bottom Line
The Marathon des Sables 2026 is not just a race. It’s a week-long reckoning with your own limits, played out across some of the most striking terrain on the planet. Whether you choose the Legendary edition in April or start with the shorter autumn formats, what awaits you is an experience that reshapes how you think about your body, about nature, and about what you’re actually capable of. Morocco’s Sahara has been the iconic stage for this adventure for forty years — and there’s a reason thousands keep coming back.
The desert doesn’t wait. But it welcomes anyone brave enough to show up.
